Decommissioning of Head & Sink & Shower Drains Together 2009
This year I figured out a much easier way without having to detach ANY hoses
They key is to close the seacock and pump the antifreeze backwards into the bowl
First I'm sure you know know that under the sink in the head...
- When Y valve is connected up & to starboard, the sink drains
- When Y valve is connected up & to port, the shower sump drains
- Both are pumped upwards, through a strainer, to a line that connects to the inlet line from the seacock to the head.
1. I pumped out at the pump-out station and rinsed 3 times with water
2. I removed and cleaned the filter under the sink
3. I turned the Y valve to connect with the shower sump and poured antifreeze into the shower sump and turned on the sump pump until I saw that the pink antifreeze reached the bowl of the filter
4. I poured antifreeze into the bottom of the refrigerator, turned the Y valve to the refrigerator drain, and turned on the pump until I saw antifreeze go into the bowl of the filter and the out thru the seacock (I have a semi-transparent reinforced PVC hose that leads to the seacock)
5. I cleaned the filter again of junk that had drained from the refrigerator
6. I closed the seacock thus preventing any antifreeze from exiting through the seacock & therefor routing the antifreeze into the bowl of the head
7. I added antifreeze to the shower sump & turned the Y valve to the shower sump position.
8. I turned the lever of the head to the "Flush" or fill bowl position
9. I turned on the pump and simultaneously pumped the head to add antifreeze into the bowl; it came in readily (but did not come in when I pumped the head w/o the sump pump on probably because the line had air in and thus wasn't primed)
10. I turned the lever to "Dry Bowl" and flushed about half a gallon into the holding tank
11. Then I poured half a gallon directly into the head via the deck pump out hose
12. Then I opened the macerator seacock and turned on the pump until & a fair amount of holding tank antifreeze went through the lines
I hate having to take my wife's hair dryer to try to pry off the hoses and this eliminated all that and it was very easy. If you've already using this method... NEVER MIND.
